Barrier isn't a DPS weapon, it's support. Max dynamic is an absolute must. Then caliber, with leftover points in lethal.

Thank you for the input! I understand that Barrier isn't meant to be a dps weapon, but I don't feel that a max reload is absolutely necessary. At least with the games that I've been playing with Barrier, I feel that a reload speed of lvl 10 was good enough for me, so I want to focus on DPS for now.

IMO the gun has quite a slow base reload. But if you feel reload is sufficient, that's totally your prerogative.

Just remember Dynamic boosts both the reload (which is required for dropping the shields, since it drops the mag) AND the fire rate. More bullets put out = more DPS, and less time spent in reload animations = more time spent shooting.

Also consider this- even though the DPS is low compared to other weapons, the ability to completely nullify all incoming damage means it will win any DPS race. Kon or Schneider shooting at you? Drop a shield and their DPS becomes 0, you will win that firefight. I personally consider it an extremely frustrating and OP weapon to fight against due to the fact that, even with low shot damage, it will win any shootout, or force the enemy into CQC, which is to Mikah's advantage with her clone tricks.
